Abstract

To enable a hydrogen tank to be efficiently filled with hydrogen even when the hydrogen tank has a large capacity, hydrogen filling at the nozzle flow is prohibited when the nozzle flow of a nozzle is larger than the receptacle flow of a receptacle or when the receptacle flow is unknown under the condition that the nozzle and the receptacle can be connected to each other.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A fuel cell electric vehicle comprising:
 a fuel cell system provided with a fuel cell and a hydrogen tank;   a receptacle for connection to a nozzle, the receptacle being provided at the head of a hydrogen introducing pipe of the fuel cell electric vehicle; and   a control unit adapted to transmit information on the type of receptacle of the fuel cell electric vehicle for determining a proper flow for hydrogen filling of the hydrogen tank.   
     
     
         2 . The fuel cell electric vehicle according to  claim 1 , wherein the control unit is adapted to transmit the capacity of the hydrogen tank. 
     
     
         3 . The fuel cell electric vehicle according to  claim 1 , further comprising multiple receptacles. 
     
     
         4 . The fuel cell electric vehicle according to  claim 1 , wherein the control unit is adapted to transmit the number of the receptacle(s). 
     
     
         5 . The fuel cell electric vehicle according to  claim 1 , wherein the control unit is adapted to transmit wirelessly. 
     
     
         6 . The fuel cell electric vehicle according to  claim 1 , wherein the control unit is adapted to calculate the pressure rise rate.
